About nuts

Butterfly Wing Nut is listed under Nuts — hex, nylon-insert, flange, wing, coupling and jam nuts. Nuts are internally threaded fasteners designed to mate with a corresponding externally threaded fastener, typically a bolt or screw, to create a secure joint. Their primary function is to resist axial loads and prevent loosening.
